I know that IBKR has a good reputation. But the web version is realy altbacken (looks old and error-prone) - at least for me, someone who rarely works with it. Some things are extremely slow. For example, opening the message centre takes ~12 seconds for me. And today I was briefly startled after IBKR failed to display my positions. After a reload, they were there again.
Has it always been like this, or has it got better/worse in recent years?
Edit:
It happened again, this time I was able to look into the DevTools of Firefox.
The following request…
https://www.interactivebrokers.co.uk/portal.proxy/v1/portal/portfolio/<USERID>/combo/positions?nocache=true
is answered with an HTTP 500 and the message {"error": "Not ready"}. However, the IBKR interface interprets this as “No positions” instead of displaying a reasonable error.
Hopefully a temporary problem.
